Great replacement/upgrade for proximity cards and readers – add cutting edge security, encryption, site-specific passwords, and encryption keys, mobile application capability and save 30% on card costs. Keep your current Wiegand format and card numbering.
Universal replacement readers – easy to install with standard wiring, quick-connect wiring harness (mullion reader), or spring-loaded insert terminals (wallswitch reader) and mounting plate.
Aesthetically pleasing with modern shape and color to match any facility’s decor.
Priced competitively with industry leading single technology readers.
Wiegand output allows the reader to interface with most access control systems.
Mullion mount reader is IP-65 certified – excellent performance in dusty or wet conditions.
Determine the Wiegand format and card numbering used by your current system.
Using the ProxWriter III™ System, select a password, and encode D24Secure NFC™ cards with the same card numbers and formats(s) used by your current system.
Program your new D24Secure NFC™ Universal Replacement Readers with the selected password, and then replace your current proximity readers by using the existing Wiegand cabling and matching the wire colors and functions.
Issue cards and begin using the system.
Because the D24Secure NFC™ cards and readers support your current card numbering and Wiegand format, there is no need to reprogram your access control system.
- For example, you may need to merge a system using 26-bit Indala cards, and another system using 37-bit Simplex format cards. Since both systems use a Wiegand interface, the readers can be replaced with D24Secure NFC™ readers.
- The Indala 26-bit cards have a fixed facility code and sequential ID numbers, and the Simplex cards have large sequential ID numbers with no facility code.
- The Simplex and Indala fomratted numbers are encoded on each card with their own passwords (using the ProxWriter III™ system).
- The appropriate passwords are programmed into each D24Secure NFC™ reader based on the connected system.
- When the cards are presented, the reader simply checks the password to select and output the correct format to each system.
Note that while different systems can use different formats, they could also have the same format and different numbering schemes or facility codes.
- If it supports any of the leading brands of Wiegand output proximity readers and cards, it can support smart and multi-technology readers and cards.
- Note that other reader technologies use Wiegand data, such as Barium Ferrite, Bar Code, Mag Stripe, or actual Wiegand Wire Swipe readers, so these systems can also be upgraded to D24Secure NFC™.
- This applies only to the access control data stored on the card. Third party applications such as cashless vending or time and attendance generally require a smart reader with bidirectional communications interface, such as USB, RS232 or RS485.
Multi-technology readers can read low or high frequency cards and different prox formats, but unlike multi-format readers, they do not have the capability of selecting and sending the correct data to the correct system in a multi-system scenario.
It continuously transmits its pre-programmed card number when held in the RF Field created by a Proximity Reader.
Proximity technology uses 125 KHz radio frequency and is referred to as Low Frequency or LF card technology.
Proximity chips have a very small memory, generally around 256 bits.
Proximity chips have little or no data security. . Typically the raw unencrypted card data is transmitted to the reader.
With proximity, data only flows in one direction – from the card to the reader.
When held in the RF Field created by a Smart Card reader, it has an intelligent two-way dialogue with the reader, including various steps such as anti-collision, mutual authentication, key verification, requests for data transmission, reading and writing to specific locations on the card chip, encryption and decryption, incrementing or decrementing stored values and much more.
Contactless Smart Card technology uses 13.56 MHz radio frequency and is referred to as High Frequency or HF card technology.
Contactless Smart Card chips have much more memory than prox chips, ranging from 1 kbit to 32 or more kbits.
Contactless chips have state of the art security and encryption.
With contactless smart cards, when a card is presented to the reader there is an encrypted dialogue between the card and reader called mutual authentication, where the reader verifies that a legitimate card is being used, and the card verifies that it is being read by a legitimate reader (as opposed to an illicit skimming device, for example).
Then the card and reader passwords are checked, and if the card contains multiple formats, the reader chooses the correct format, decrypts the data and transmits it to the access control system.
Access is either granted or denied by the access panel.
In third party applications, the reader can also write to the card, which is useful for transit, cashless vending or cafeteria payment applications where the card is loaded with stored value, which is then decremented with each use or purchase.
D24Secure NFC™ smart technology adds multiple layers of security to readers, credentials, and Mobile applications.
D24Secure NFC™’s forward compatibility is based on using an open platform that easily adapts as new innovations enter the marketplace.
ISO 14443 transmits data up 4 times faster than ISO 15693.
ISO 14443 cards have a shorter read range for security, but faster data transfer speeds than ISO 15693 cards.
Most future innovation and third-party applications are being developed for ISO14443, rather than for ISO15693. ISO 15693 cards are not NFC compatible, and cannot be read by Mobile Devices.
D24Secure NFC™ also allows you to store cardholder information which can be read by Security, Administrators or First Responders by using the DigiOn24 App on any NFC-Compatible Android device.
